• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Through Hole (exact match required)
• Response Time: Medium Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 100A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Both substitute parts listed below satisfy all mandatory parametric requirements and are manufactured by Littelfuse Inc., ensuring design and performance compatibility with circuits originally specified for the 0232002.MXE.

Parameter Comparison

Engineering Selection Recommendations

Both 0232002.MXEP and 0234002.MXEP are direct parametric equivalents to the obsolete 0232002.MXE and are suitable for replacement in applications requiring 2A 250VAC glass cartridge fuses with 5mm x 20mm axial through-hole mounting.

0232002.MXEP is recommended for applications where regulatory compliance with CE, KC, and PSE certifications is required. This part maintains ROHS3 compliance and offers the closest DC cold resistance value (0.037 Ohms) to the original part.

0234002.MXEP is recommended for applications requiring the broadest regulatory approval coverage, including CE, CSA, K-MARK, PSE, and UL certifications. This part is suitable for markets with stringent international safety standards and provides ROHS3 compliance with REACH unaffected status.

Both substitute parts are active products with confirmed inventory availability, eliminating supply chain risk associated with the obsolete main part number.

Frequently Asked Questions (FAQ)

Q: Can 0232002.MXEP and 0234002.MXEP be used interchangeably with 0232002.MXE?

A: Both substitute parts are parametrically equivalent to the main part across all critical electrical and mechanical specifications, including current rating, voltage rating, package dimensions, mounting type, and response time. Direct substitution is supported without circuit modification.

Q: What is the difference between the two substitute parts?

A: Both parts meet identical parametric requirements for circuit functionality. The primary differences are regulatory certifications (0234002.MXEP includes UL and CSA approvals in addition to CE, KC, and PSE) and melting I²t values (8.25 for 0232002.MXEP versus 9.97 for 0234002.MXEP). Selection depends on regional regulatory requirements and application-specific thermal characteristics.

Q: Are the substitute parts RoHS compliant?

A: Both 0232002.MXEP and 0234002.MXEP are ROHS3 compliant, whereas the original 0232002.MXE is RoHS non-compliant. This compliance improvement is an additional benefit of substitution.

Q: Do the substitute parts have the same physical dimensions?

A: Yes. All three parts share identical package dimensions of 5mm x 20mm (Axial) with 0.228" diameter and 0.886" length, ensuring mechanical compatibility with existing through-hole footprints.

Q: What is the inventory status of the substitute parts?

A: 0232002.MXEP has 699 pieces in stock, and 0234002.MXEP has 741 pieces in stock, both classified as new original inventory with active product status.
